# Adopting Chroma Key

The **Chroma Key** is a common method used to remove the background from a webcam source. It requires a solid-colored chroma key cloth, such as green or blue, to be physically set up behind the user. If an object with a similar color to the chroma key cloth is visible, it may become partially or entirely transparent, resulting in an unintended appearance.

Alternatively, you can use the **Virtual Background** feature in PRISM Lens. This automatically removes the background without requiring a physical chroma key cloth. For more information about Virtual Background, refer to the following pages:

* **PRISM Lens -** [getting-started-with-prism-lens](https://guide.prismlive.com/lens/guides/getting-started-with-prism-lens "mention")
* **PRISM Lens -** [using-virtual-background](https://guide.prismlive.com/lens/guides/features/virtual-background/using-virtual-background "mention")

When comparing Chroma Key with Virtual Background, Chroma Key consumes fewer computer resources and provides a clearer subject outline. Try testing both options separately and choose the one that best fits your needs.

To set up Chroma Key, double-click on the source where you want to apply it to open the Properties window. Then, click the **Filters** button at the bottom of the source properties window. You may need to scroll down to find the button depending on the properties. You can also access the Filters button from the context menu by right-clicking the source.

Set the **Key Color Type** option to match the color of your chroma key fabric.

If the subject and background are not separated as cleanly as expected, adjust detailed settings such as **Similarity**, **Smoothness**, **Key Color Spill Reduction**, and more. Setting the **Opacity** option to 1 will remove the background completely, making other sources behind it visible.
